Folded Absorbent Article with Orthogonal Release Paper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent articles for hygiene products, such as sanitary napkins and pantyliners, are typically packaged in plastic wrappers that are not environmentally friendly and contribute to plastic waste.
Innovation Solution
The use of a release paper that is orthogonal to the longitudinal direction of the absorbent article to maintain the article in a folded configuration, eliminating the need for a plastic wrapper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic wrapper is used to package the absorbent article, then the structural integrity and protection of the article is maintained, but the environmental impact increases due to plastic waste
Solution Approach 1:
The invention extracts and removes the plastic wrapper from the packaging system, retaining only the essential protective function through the release paper and adhesive layers. This eliminates the harmful plastic component while maintaining the necessary protection and structural integrity of the absorbent article.
Solution Approach 2:
The invention changes the material parameter from petroleum-based plastic to biodegradable release paper, fundamentally altering the environmental characteristics of the packaging while maintaining its protective function. This parameter change transforms the harmful plastic waste issue into an environmentally friendly solution.
2Object-affected harmful factors
If a plastic wrapper is used to package the absorbent article, then protection against contamination is provided, but the quantity of material used increases
Solution Approach 1:
The invention removes the plastic wrapper material entirely, replacing it with a minimalistic release paper and adhesive system that provides equivalent protection against contamination without the excessive material consumption associated with traditional plastic packaging.
Solution Approach 2:
The invention changes the material composition from plastic to release paper, which provides sufficient protective functionality with significantly reduced material quantity. This parameter change in material type directly reduces the quantity of substance used while maintaining protection against contamination.
3Object-generated harmful factors
If a release paper orthogonal to the longitudinal direction is used, then the need for a plastic wrapper is eliminated, but the complexity of the packaging structure increases
Solution Approach 1:
The invention introduces a dimensional change by positioning the release paper orthogonal to the longitudinal direction of the absorbent article. This dimensional reorientation allows the release paper to effectively maintain the folded configuration and provide protection without requiring a traditional plastic wrapper, thus reducing environmental impact.
Solution Approach 2:
The release paper structure serves multiple functions simultaneously: it maintains the folded configuration, provides protection against contamination, and eliminates the need for additional plastic wrapping. This multi-functionality reduces the overall complexity by consolidating multiple packaging requirements into a single integrated structure.
